We are going to WDW in December and plan on getting a wheelchair from Pop Century for my Mom so that she doesn't get too tired walking around the parks (she's 81). I'm just wondering what happens if a resort wheelchair goes missing. I know if you have a rental from the theme park, that they will replace it for you, but not sure if it is the same for resort wheelchairs. Would we be responsible for the cost of the wheelchair? Also, should we bring a bike lock from home to lock the wheelchair or are they available from the resort? Thanks for any info you can give me.
